Hey all fitted decat last wknd full 3" back with rear silencer and on my previous runs upto St Neots from slough I'd average 28 on the mway but this wknd I averaged 34 same speed same route is this something anyone else has experienced thanks
Are you driving it the same. Things like exhaust mods/air filters can lead to worse economy as you gain a heavier right foot due to the noise.
Drive the same slow like an snail only blast it if I need it so should be ok for say a month only use it for 12 miles a week
I doubt very much it will be detrimental to an engine. Yeah it's not optimum buy how much does a decat actually affect the fuelling?
Quite a lot if fuel economy goes up.. It's always best to have it checked on a dyno for afr and safeness and it will need mapping.. Like said damage can be done internally ie det ect.. ya just need to be careful can soon crack a ring land or do a valve in very easy buddy
